Configuring the management address and its encoding format
LLDP encodes management addresses in numeric or character string format in management address
TLVs.
By default, management addresses are encoded in numeric format. If a neighbor encodes its
management address in character string format, you must configure the encoding format of the
management address as string on the connecting port to guarantee normal communication with the
neighbor.
To configure a management address to be advertised and its encoding format on a port or group of
ports:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter Ethernet interface view
or port group view.
• Enter Layer 2/Layer 3 Ethernet
interface view:
interface interface-type
interface-number
• Enter port group view:
port-group manual
port-group-name
Use either command.
3. Allow LLDP to advertise the
management address in
LLDPDUs and configure the
advertised management
address.
lldp management-address-tlv
[ ip-address ]
Optional.
By default, the management
address is sent through LLDPDUs.
• For a Layer 2 Ethernet port, the
management address is the
main IP address of the lowest-ID
VLAN carried on the port. If
none of the carried VLANs is
assigned an IP address, no
management address will be
advertised.
• For a Layer 3 Ethernet port, the
management address is its own
IP address. If no IP address is
configured for the Layer 3
Ethernet port, no management
address will be advertised.
4. Configure the encoding
format of the management
address as a character string.
lldp management-address-format
string
Optional.
By default, the management
address is encapsulated in numeric
format.
Setting other LLDP parameters
The Time to Live TLV carried in an LLDPDU determines how long the device information carried in the
LLDPDU can be saved on a recipient device.
